"He just looks very, very sad," an employee at a local store exclusively tells In Touch. "He used to be so friendly and chatty, just like he was on TV. Now he keeps his head down. You can tell he's not really in the best place."

Another neighbor says Matt isn't ready for his closeup, so to speak. "He doesn't look like he did when he was on TV," this Hamptons resident reveals. "He's skinny… It looks like he's aged 10 years."

And a third neighbor says the former anchor is flying solo, with wife of 19 years Annette Roque noticeably absent: "I used to see him out with her, but never anymore. He's usually by himself."

As In Touch reported last month, Annette has already left Matt. "She called him and told him that she was divorcing him," a source told the mag. "Annette didn't give Matt the chance to beg and plead like he has for years. She told him her lawyer would contact him, and then she hung up. Simple as that."

These days, as her husband apparently wallows in despair, Annette has been enjoying a fresh start overseas. "She's taken off her wedding ring and has been living the high life in Europe," the source added. "She's acting like a woman who has already moved on from a hellish marriage."

With his life in such dire straits, Matt reportedly wants to take other media bigwigs down with him. In Touch has learned he's writing a tell-all that will double as a burn book. "Matt will name powerful men he knows, some famous, who did the same thing he did," an insider says. "He will expose people. He knows all their dirty secrets … He realizes that the juicier the story, the bigger the payday."

A big payday will inevitably get Matt out of any doldrums he's weathering. But we're not sure America is ready to see him smiling again.
